I '0 all whom it may concern.

Be it known that I, JOSEPH Errs, a citizen of the United States,residing at Williamston, in the county of Anderson and State of SouthCarolina, have invented certain new and useful Improvements in aLoom-Bobbin Holder, of which the following is a specification.

An object of the invention resides in providing a bobbin holder forbobbin batteries of looms which has the yieldable latch memberprojecting partially across the discharge opening of the battery foryieldably supporting the bobbins in the battery, and yet permitting theforcible discharge of a bobbin in the usual operation of the loom forfilling a shuttle and for preventing accidental discharge of the bobbinsfrom said battery.

A further object of the invention resides in providing a yieldablebobbin holder having means to permit the adjustment of the projection ofthe latch member relative to the bracket member for adapting a singleholder to use on different looms having variations in the structure ofthe bobbin batteries, so that the latch member may be projected theproper distance across the discharge opening of the battery .for propercooperation with the bobbins in said battery to yieldably support thesame.

A further object of the invention resides in the provision of such aholder which is comparatively simple of construction, inexpensive ofmanufacture, and of such a nature as to be readily attached toconventional types of bobbin batteries employed in conjunction withweaving machines.

The nature and advantages of the invention will be better understoodwhen the following detailed description is read in connection with theaccompanying drawings, the invention residing in the construction,combination, and arrangement of parts as claimed.

In the drawings, forming part of this application, like numerals ofreference indicate similar parts in the several views; and whereinFigure 1 is an inside end elevational view of a conventional type.bobbin battery, showing my improved holder mounted thereon.

bin outlet C, together with the bobbin guide D forwardly of this outlet.The casing constituting the battery is formed behind the outlet openingU with an extension E, in the form of a web, and to this extension issecured my improved holder designated in general by the numeral 5.

With reference particularly to Figures 2,

3, and 4, it will be noted that the improved bobbin'holder, includes abracket member 6 formed of a strip of material bent into U- shape toprovide a pair of parallel legs 7 joined by the connecting portion 8.The bracket member is formed at 9, .in the portion 8 with a squareopening, while the legs 7 are formed with longitudinally extending slots10 for a purpose which will now be described. The bracket memberreceives a bolt 11 having a squared portion 12 adjacent the head, whichfits in the square opening 9, so that when the bolt is mounted in theopening in the web of the bobbin battery, the bracket member will besecurely fastened thereon and held against rotation on the bolt by thesquared portion 12.

Extending longitudinally of the keeper 6 is a-sliding latch bolt 13,which is-slidably disposed within the said slots 10 of the end legs 7 ofthe keeper 6. One end of this sliding latch bolt 13 is formed with ahead or plate 14, which is curved downwardly,

as clearly shown in Figures 1 and 3. The

latch member 13 is made of strip material and has the edge portions cutaway to 'form the shoulders 15 at the opposite edges of the member. Awasher plate 16 is formed with a central opening so that it may befitted on the latch member and engage the shoulders. A coil spring 17 ismounted on the latch member between the plate 16 and one leg of thebracket member and is normally held under compression.

The end of this member 13 opposite from 'brac-ket member for adjustab-lymounting the projection of the latch member into the discharge openingof the bobbin battery, in a predetermined manner, so that adjustment mabe made for different sized bobbins usec in one loom' or when the invention is to be app-lied to other looms.

Referring particularly to Figure 1, it will be seen that the extensionweb of the battery A is formed with an opening I through which isinserted the bolt 12 of my bobbin holder, the same beingrigidly securedthrough the instrumentality' of a nut 20. When my holder'is positionedas shown in this figure, it will be seen that the head '14 of the latchbolt 13' will be normally projected by the coil spring 1?, partiallyacross the discharge opening C of the bobbin battery to a pointdetermined by the adjustment of the cotter pin 19, so that it willyieldably engage and support the lowermost bobbin in the battery andprevent the accidental discharge thercof, and yet will readily yield tothe forcible discharge of the bobbin by the means provided forthispurpose The adjustability of the operative position of the latch memberrelative to the bracket member provides a construction which permits theapplication of the device to different looms and the projection of thelatch member placed at the proper point, or the adjustmentot the latchmember on one loom, when the size of the bobbin is changed to properlycooperate in the support of the different sized bobbin. The provision ofthe bracket and latch members formed of sheet material, provides astructure which may be manufactured at small cost and yet operateefficiently.

Although I have herein shown and described the preierred embodiment ofthe present invention, it is nevertheless to be understood that minorchanges maybe made therein, without departing from the spirit and scopeof the invention as claimed.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is; I 4

1 The combination with the bobbin batt'e'ry of a: weaving machine havingan outlet opening for the bobbin, of a bobbin holder incliidii' ga U-shaped bracket member formed with openings in the parallel leg portionsthereof, a latch member slidalbly mounted in the opening of the bracketmember having a shoulder formed thereon, a resilient member engaging theshoulder on the latch member and the bracket member for projecting thelatch member into the opening in the bobbin battery, agd 7 meansadjustably controlling the projection of the latch member in apredetermined manner.

2. A bobbin holder for bobbin batteries of Weaving machines, comprising'a stationary support on said bobbin battery, a latch member slidablymounted on the support and resiliently projected into the outlet openingof the bobbin battery, said latch member being formed with a pluralityof openings arranged in a predetermined manner, and means adapted to bemounted in any one of said openings in said latch member for engagingsaidsupport and limiting the projection of the latch member into saidoutlet opening.

3. A bobbinholding attachment for bobbin batteries of weaving machines.having outlet openings comprising a U-sliaped bracket member detachablymounted on the bobbin battery, a latch member slidably mounted in thelegs of the bracket member having a shoulder thereon normally betweenthe legs, a resilient member engaging the shoulder at one end and one ofthe legs at the opposite end for normally projecting the latch memberinto the outlet opening of the bobbin batter and means for adjustablycontrolling t'e projection of the latch member into the outlet opening.

4:. A bobbin holding attachment for bobbinbatteries of weaving machines,said batteries having out-let openings comprising a U-shaped bracketmember detachably mounted on the bobbin battery, a latch member slidablymounted in the legs ofthe bracket member, resilient means engaging thebracket member and the latch member for normally projecting the latchmember into the discharge opening, and means adjustably mounted on thelatch member, for cooperation with the bracket member for predeterminingthe projection of said latch member by the resilient means.

5. A bobbin holding attachment for bobbin batteries of weaving machineswherein said: batteries have outlet openings comprising a U-shapedbracket member formed of sheet material detachably secured to the bobbinbattery, a latch member formed of strip material slidably mounted in theleg portions of the bracket member, said latch member having ashouldered portion between the legs of the bracket member, resilientmeans mounted on the latch member between the shouldered portions andone leg of the bracket member for normally projecting the latch memberinto the outlet opening of the bobbin battery, and means adjustablymounted on the latch member for limiting the projection thereof in apredetermined manner.

In testimony whereof I hereunto a t-fix my Signature.
